Before you go
This trip requires Mexican auto insurance — U.S. policies don’t count south of the border.

Halfway down the peninsula, the desert does something impossible: an underground river surfaces into a lagoon ringed by a hundred thousand date palms, and a lava-stone mission town sits in the middle of it. San Ignacio would justify the drive by itself. But it’s also the gateway to the Sierra de San Francisco — the UNESCO-listed canyons where the Great Mural rock art covers cave walls with life-size figures painted across some 7,500 years — and that combination makes this the library’s deepest trip in every sense.

Before you go — read this

Baja changes. Roads wash out, camps close, a Pemex that was there in March can be dry in November. Everything on this page came from members who actually drove it, on the date stamped at the top — but conditions on the ground are yours to verify.

The GPX track is a planning aid, not a navigation authority. Don’t follow a line on a screen into terrain you can’t see. Carry paper backup, tell someone your plan, and turn around when the road tells you to.

Mexican auto insurance is required by law and your U.S. policy doesn’t cover you. If something goes wrong without it, the situation gets much worse very fast. Get a quote before you cross.
